A method of alkylating a hydrocarbon stream including: providing a feed stream that includes hydrocarbons and ionic liquid catalyst; passing the feed stream through a low efficiency mixer to create a mixed stream, whereby the low efficiency mixer creates droplets within the feed stream that are primarily within a predetermined size range; passing the mixed stream and an olefin stream into a reactor; performing an alkylation reaction within the reactor, thereby forming a reacted stream; and separating the reacted stream into a settled ionic liquid catalyst stream and a hydrocarbon stream through the use of at least one hydrocyclone.
